From the starting position, slowly bend over at the waist until your upper body is at a 90-degree angle to your legs. Keep your back as straight as possible and your neck in line with your spine throughout the movement. As you descend, allow the dumbbells to hang straight down in front of you (see Photo 2).

When your upper body is at a 90-degree angle and the weights are in front of you, perform a dead row. To do a dead row, use your upper back muscles to pull the dumbbells up to your chest (see Photos 3 and 4).

When you have brought the dumbbells up to your chest, reverse the motion and slowly lower them back down until your arms are hanging straight down (see Photo 5).

From the bottom of the dead row, use your hamstrings and glutes (butt) to lift your body back up to the starting position. Remember to engage your lower back and abdominal muscles as you lift to stabilize your core. The weights will follow you back up to starting position (see Photo 6).
